Vehicle Device Holder With Elastic Blocking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional device holder assemblies for mobile electronics in vehicles require complex procedures for changing between use and stowed positions, often necessitating additional support to prevent the device holder from accidentally swiveling back into the stowed position, which can be inconvenient and prone to errors.
Innovation Solution
A device holder assembly with a stowage mechanism and blocking mechanism that allows smooth transition between stowed and use positions, featuring a guide rail system, pivotable stage, and elastic blocking elements to securely hold the device in place without needing additional support, enabling easy handling and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional device holder assembly is formed as part of a compartment with a roller shutter, then the device holder can be stowed away to prevent theft indication, but the process of changing between use and stowed positions becomes complex and inconvenient
Solution Approach 1:
The device holder is extracted from the compartment and can be swiveled out independently. The blocking mechanism is extracted as a separate functional element that automatically engages to prevent accidental retraction. This separation allows the holder to be used without requiring the compartment to remain closed or the shutter to be manipulated.
Solution Approach 2:
The blocking mechanism automatically engages when the device holder is in the use position, providing self-blocking functionality without requiring user intervention. The mechanism self-activates based on the holder's position, eliminating the need for users to manually support or secure the holder during use.
2Reliability
If additional support mechanisms are added to prevent accidental swiveling back, then the device holder can be secured in use position, but the device complexity increases
Solution Approach 1:
A blocking element acts as an intermediary between the device holder and the stowage mechanism. This blocking element engages with a blocking mechanism to prevent accidental retraction, providing a simple mechanical intervention that adds reliability without requiring complex control systems or multiple components.
Solution Approach 2:
The blocking mechanism is designed to preemptively prevent accidental swiveling back by automatically engaging when the holder reaches the use position. This preliminary anti-action counteracts the potential harmful motion before it can occur, ensuring position stability without requiring continuous monitoring or control.
3Ease of operation
If the device holder is designed to be easily movable for frequent changes, then the ease of operation improves, but the risk of accidental retraction into stowed position increases
Solution Approach 1:
The device holder is designed with dynamic characteristics, allowing smooth movement during intentional transitions between stowed and use positions. The blocking mechanism dynamically engages and disengages based on the holder's position and user intent, enabling easy handling when moving intentionally while preventing accidental retraction through automatic blocking.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates convenient and secure handling of the device holder by allowing smooth stowage and deployment with minimal user actions, ensuring the device is securely held without accidental retraction, even in cramped spaces, and accommodating various device sizes and shapes.
Implementation Method 1
an elastic element extending from the first holding element to the blocking element, wherein the blocking element is configured to block the stowage movement when pulled in the first direction by the elastic element

AI summary
A device holder assembly includes: a device holder holding a mobile electronics device; a stowage mechanism performing a stowage movement to transition the device holder between a stowed position and a device holding position; and a blocking mechanism which blocks the stowage movement from transitioning the device holder to the device holding position when the mobile electronics device is held by the device holder.
